Description
Invention field
The present invention relates in the communication system, particularly controlling such as the power in code division multiple access (CDMA) system of UMTS system (W-CDMA).More particularly, the present invention relates to the aspect of high-speed packet downlink packets access communications (HSPDA).
Background
As everyone knows, in the direct sequence cdma system of broadband, signal is made up of the different pseudo-random binary sequences of modulated carrier.Therefore, the wide frequency ranges of the spread spectrum of signal a plurality of channel sharings in the system.Owing to the direct sequential encoding reason, orthogonality between signals is achieved, thereby can decode separately to signal from common frequency range.
This cryptoprinciple has many advantages.For example, the direct sequence spread spectrum coding has reduced the seriousness of multipath fading significantly, and this is effectively used frequency spectrum resource.
Because the same space in signal acquisition frequency/time-domain, therefore, the accurate power adjustments of each channel is an importance of cdma system.
Cdma system all adopts power control on up link and down link.A purpose of power control is each the travelling carriage reflector that is adjusted in operation in the cell site base station receiver, makes signal have identical power level and not consider the position or the propagation loss of corresponding mobile station at base station receiver.It should be noted that power level and transmission data rate are proportional.
When all the travelling carriage reflectors in the cell site are subjected to so controlling, then equal specified received power and multiply by travelling carriage quantity in the total signal power of base station receiver.
Each the selected signal that receives in the base station is converted into the signal of carrying narrow-band digital information, and other not selected signal constitutes broadband noise signal.Yet the bandwidth minimizing of carrying out according to decode procedure is increased to permission can accept the level of error rate operation with signal to noise ratio from negative value.
For example the entire system capacity of the number of users that can operate simultaneously in the sub-district depends on the given minimum signal to noise ratio of accepting the error rate of generation.
On down link, the sub-district is also supported power adjustments by the request of response travelling carriage for adjusting downlink power to each signal of corresponding mobile station.Purpose for fixing, near cell site, be subjected to multipath attenuation and shadow effect to influence unit very little or that run into the very little interference in other sub-district to reduce power.Therefore, whole noise level reduces, and those travelling carriages in difficult circumstances more will be benefited.
Third generation mobile system, current the 3rd generation partner program (3GPP) the standard support that also is called UMTS are used for the different user data rate of different user.By the request service quality of the interference level in the real cell, general channel quality, user data rate and transfer of data, be identified for the transmitting down link power of given user subject.
In the UMTS system, there is the physical channel of two kinds of fundamental types to be used for transmission: dedicated channel and common signal channel.Once have only a user can use dedicated channel, and many users can share common signal channel.
Usually, the dl interference of particular user entity comes from a plurality of transmission of the lower-wattage of (on other orthogonal channel) other user subject.Interference comes from adjacent base station and therefrom receives the base station of transmission in the user subject of carrying out being considered just under the case of soft handover.
Transmitting power control (TPC) ring is used for dedicated channel.The purposes of TPC ring is to be that each user subject is regulated downlink power, even so that received power under the situation that the absolute value that disturbs fluctuates, also keep constant with ratio between disturbing.Therefore, can obtain required user's downlink data transmission quality.
The TPC ring utilizes each time slot (1 time slot is corresponding to 0.67 millisecond) once to be forwarded to the TPC order of base station from user subject.The TPC order is " rising power " or " reduction power " progressively.The power step size adjustment of each order is generally 1dB.This means TPC ring each time slot adjustment through-put power 1dB at most.Therefore, will be owing to from the variation of the variation of the interference level in other source and channel quality and along with the time changes from the power of base station.The utilization of TPC ring will cause the more constant interference level of individual consumer's entity considered.
Recently, a kind of new downlink service, high-speed downlink packet access (HSDPA) in 3GPP, have been introduced.In " having the aspect of performance that high-speed downlink packet inserts the WCDMA system of (HSPDA) " (Perfbrmance Aspectsof WCDMA Systems with High Speed Downlink Packet Access (HSPDA)) that the people showed such as T.E.Kolding, can find the cutline of operating principle.
The HSPDA transmission utilizes 2 milliseconds of Transmission Time Intervals (3 time slots), adaptive modulation and coding (AMC) the multi-mode transmission as QPSK and 16QAM modulation, fast physical layer (L1), mixing request (H-ARQ) automatically.Scheduler is transferred to usually said Node B, also is expressed as base station apparatus BSS from radio network controller.In Fig. 6, provide the sketch map of the transfer of data, up-link power control and the downlink power control that are indicated to various user subject UE.
Fig. 1 illustrates the main channel that utilizes among the HSPDA.
On down link, provide: some common data channels 1.Be used to use each user's of HSPDA transmission special signal radio bearer 2; Be used to control the common signal channel 3 of signaling, a plurality of common user data channels 4-5 distribute the HSPDA data with flexible way for it.
On up link, provide: except that other function, be used to provide the dedicated channel 6 of channel quality information CQI and the automatic demand signalling H-ARQ of HSPDA, the up-link that comprises control information and data 7 that is associated with each HSPDA user.
After introducing high-speed downlink packet insert (HSDPA) in the UMTS system, interference level will be no longer fluctuates in mode slowly.When the HSDPA channel when free of data transmission changes to the maximum data rate transmission, the big instantaneous interference steps of some dB will appear.Other travelling carriage will run into performance degradation greatly when high power HSPDA transmission start.This problem often is described to " flash light effect problem ".
In Fig. 2, the exemplary scenario of the downlink interference level that is used for typical user's entity is shown.User subject runs into the thermal noise N_TH of certain level.Also has interference I_ADJ from the downlink channel of neighbor cell.In addition, the non-HSPDA from other downlink channel in the given user subject sub-district of living in infers that I_NON_HSPDA_CELL also influences interference level.Compare with preceding two described sources, back one level often is sizable level.At last, interference I_HSPDA_CELL from the HSPDA of non-adjusting transmission is shown.As mentioned above, these transmission may be high-magnitude, and can change rapidly.
In Fig. 3, Fig. 1 HSPDA transmission corresponding to the HSPDA power that uses in the Node B is shown further.
In Fig. 4, the summation D_PWR of Fig. 2 interference component that is used for unadjusted HSPDA transmission is shown.Given actual dedicated channel wattmeter is shown A_PWR.Change because TCP satisfies the maximum of 1dB/0.67 millisecond, therefore, the uplifted side that general signal interference level S/I_1 disturbs in the HSDPA generation can drop to and be lower than given minimum detection threshold value.

As mentioned above, the closed loop of the condition of acceptance of the travelling carriage of considering according to depending on (TPC) is adjusted in the down-link transmitting power on the special-purpose non-HSPDA channel, regulate according to this, allow the growth rate of transmitting power to be restricted to predetermined first value of each chronomere at least.In cdma system, terminal can be asked each time slot growth or be reduced the down-link transmitting power of 1dB, that is, and and with the speed 1dB/0.67 millisecond of maximum.
Decide on real system, another speed may be fit to.
High-speed packet data transmission has the attribute that is not subjected to the restriction of TPC ring Consideration.
HSDPA is a kind of service, wherein the definite data volume that will launch of Node B (base station) and the through-put power of use.The data volume of launching changes with available transmission power.Per the 3rd time slot (=2 milliseconds) has new HSDPA transmission.
The function of Node B is as follows: air interface transmission/reception; Modulating/demodulating; CDMA physical channel coding; Micro diversity; Mistake is handled; Closed power control (TPC).
The function of RNC is as follows: radio resource control; Permission control; Channel allocation; The power control setting; Switching controls; Grand diversity; Encrypt; Segmentation/reorganization; Broadcast signaling; Open Loop Power control.

The corresponding power control unit PWR_CTRL that is used for corresponding dedicated channel responds to corresponding closed-loop power adjustments signal TCP_CMD, and the rate of change of transmitting power is restricted to the predetermined value of each chronomere at least in this case.
First and second data that power amplifier will be dispatched are amplified also output, and Shu Chu first and second channels are subjected to the influence from each other interference thus.
Each corresponding power control unit responds to the corresponding closed-loop power re-quest commands (TCP_CMD) from each user subject.
The signal P_DATA23 of the power level of the power output of summing stage SUM report index signal DATA23 is provided to dump power with this signal and determines level DET_REM.
Because power output P_OUT may be subjected to other restriction of governing stage or be subjected to the restriction of the physical constraint of power amplifier at least, therefore, has the limited power level budget P_OUTMAX that can be used for total transmission.Dedicated channel and common signal channel DATA2 and DATA3 are owing to the function that it is provided for voice and control signaling has higher priority, therefore, signal P_REM is defined as P_OUTMAX-P_DATA23, and indication is available dump power after the scheduling of common signal channel and dedicated channel and power division.This signal determines that from dump power level DET_REM provides, and is transported to HSPDA scheduler HS_SCHDR.

The measurement that 5-is expressed as permission power P _ PERM (t) given example be confirmed as with the actual power (P_HS (t-1)) of the last example of predetermined value (d) addition or the power capability (P_POS (t)) determined in maximum; In other words, P_PERM (t) :=MAX[P_H (t-1)+d, P_POS (t)],
6-available horsepower (P_AVBL (t)) is confirmed as allowing the minimum value in power or the dump power (P_REM (t)); In other words, P_AVBL (t) :=MIN[P_PERM (t), P_REM (t)],
7-is final, decides on general input high-speed data amount according to available code and channel quality, and the scheduler schedules HRPD (high rate packet data) makes power output P_H (t) be less than or equal to definite available horsepower R_AVBL (t).
If the HSPDA transmission just starts, then value=0 of P_H (t-1) and P_POS (t-1)=0.In the UMTS system, when the TPC step-length was made as 1dB, selective value d was the value of about 3dB.Each scheduling example has the duration of TTI=2 millisecond.
What note is to determine that the step of dump power can be finished any time before step 6.
According to the abovementioned embodiments of the present invention, the difference power between two continuous HSDPA transmit is restricted, and makes the use power oblique ascension lentamente like this of HSDPA channel so that the TPC ring of dedicated channel to raise by processing power.By limiting the increment of the through-put power of using between two HSDPA transmission, with the limit interferences increment.Therefore, the transmission of dedicated channel keeps interference-free.In addition, regulate HSPDA power, make it to downslope, being benefited of TPC restricted dedicated channels, thereby strengthen the HSPDA throughput in last HSPDA transmission back.
According to another embodiment of the present invention shown in Figure 8, the transmitter unit BSS that is used for each scheduling interval of HRPD (high rate packet data) DATA1 dispatches according to step 1-5 operation HRPD (high rate packet data), and regulates actual power P_H (t) in allowing power P _ PERM (t) rather than available horsepower.
Discuss function of the present invention and effect now with reference to Fig. 9-13, these figure relate to the given hypothesis exemplary scenario of the input grouped data DATA1 that utilizes adjusting shown in Figure 8.
When scheduling example t=A, suppose with quite constant power level H (t) emission HSPDA grouped data a period of time, and dedicated channel and the HSPDA balance of power level represented as P_H (t).
In Fig. 9, calculate power capability P_POS (t) according to step 4.
In Figure 10,, the power level P_H (t-1) that uses that adds constant d has been shown in last scheduling example for explanation.
Therefore, can in figure, be expressed as P_H (t-1)+d among Figure 10 and the maximum among the P_POS (t) among Fig. 9 as the P_Perm of definition in step 5.P_PERM shown in Figure 11 (t).
In Figure 12, P_REM (t) and P_PERM (t) have been shown.Figure 13 illustrates the P_PAVBL (t) that determines as in the step 6.
For each scheduling interval, whether on having enough HSPDA data to decide at hand, scheduler is to be less than or equal to the power level data dispatching by the power level of P_AVBL (t) definition.
In Figure 14, for given input data another exemplary scenario has been shown, use the HSPDA power P _ H (t) and the power capability P_POS (t) of the time dependent use of method as mentioned above shown in it.
As shown in the figure, measure P_POS and satisfy following situation, the power ring coupling that the HSPDA transmission has so low power formation phase (build up-phase) so that dedicated channel increases.It is also indicated and use higher H SPDA power level after the HSPDA service disconnection.
